JOlNT PLATE AND BURR-HOLDER.

SPECIFICATION forming part 01 Letters Patent No. 515,224, dated February20,1894.

Application filed October 7, 1893- Serial No.48'7j469. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK HERMAN, a citizen of the United States,and a resident of Martinsville, in the county of Oopiah and State ofMississippi, have invented certain new and useful Improvements in Joint-Plates and Burr-Holders; and I do declare the following to be afull, clear, and exact descrip tion of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

Figure 1 of the drawings is a top plan view. Fig. 2 is a view of oneside of plate and burr holder. Fig. 3 is a View of opposite side of Fig.2 and Fig. 4 is a cross section.

This invention has relation to certain new and useful improvements inrailway rail joints, and is designed to provide a simple, practical, andsecure means for retaining the meeting ends of rails; and the inventionconsists in the novel construction and combination of parts, all ashereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings illustrating the invention, theletters A, A, designate the two meeting rails, which, at the jointportions are seated upon an angular joint plate. Said plate has avertical portion B which seats against the outer, lateral faces of therails, and abase portion B uponwhich the rails seat. The inner face ofthe vertical portion B of the said plate has alongitudinal projection awhich is beveled to fit snugly between the base and tread flanges of therail as shown, said projection fitting to within about one-fourth of aninch of the face of the web of the rail. The upper edge of said portionB should be about one-third of c an inch lower than the tread surface inorder to avoid interference with hollow driving wheels, and at the sametime preserve the continuity, of the rails should the latter run orseparate from each other longitudinally by reason of the breakage of thejoint bolts.

against the joint the portion B is provided with a notch or recess 1),which admits of the rails swelling somewhat at this-point withoutcausing breakage of the bolts. The base portion B of the joint plate issomewhat wider Directly.-

than the base of the rail and projects to the inside thereof, where itis provided with up ward lugs or projections c, c, which are designed torespectively engage with notches d, d in the horizontal portion of anangular fish plate 0, fitting the inner faces of the rails. Said lugs orprojections should fit closely in these notches. I prefer also to formcorresponding notches e, e in the inner base flange of the rail anddesigned to engage with the said lugs or projections c, c. The notch eshould be of such width as to just receive the lug 0, while the notch 6should be about two inches wider than the width of thelug 0' so as topermit endwise movement of the rail, should the bolts break. The lug cand notch 6 will retain the joint and support the bolts. This notchingof the rails is, however, optional, as the joint will be secure Withoutit, but it is to be preferred. The plate, 13 B,

may be of sufficient length to form either a two, or a three-tie joint.Spikes f are driven through the'plates at the inside of the rail, whileat the outside are spikes f driven with their backs to the joint plate.

g g are the usual bolts which pass horizontally through the joint plate,the rail, and the fish plate, and secured by nuts 9. To prevent the-nutfrom turning I employ alock G especially adapted to the joint. This lockconsists of a narrow plate somewhat longer than the joint plate, itsends being bent to form angular hooks h which are engaged with the spacebetween the joint plate and rails, as shown. Formed in said plate arerecesses h, one for each nut, and having each a square shoulder h forengagement with a face of the nut. At the upper corner.of each nut theplate is struck inwardly to form inward projections k which also engagewith the nut, thus forming a double lock for each nut.

' The joint constructed as above described is exceedingly strong andsecure, and should the bolts break, its safety is not destroyed.

Having described my invention, what I claim as new, and desire to securebyLetters Patent, is-

1. In a railway rail joint, the combination with the rail sections, ofthe joint plate having the horizontal base portion upon which the jointportions of the rails are seated, and

the vertical portion having a longitudinal projection beveled to fitbetween the base and tread flanges of the rail, the upper edge of saidvertical portion being slightly below the tread surface of the rail, theangular fish plate having the notches therein, and upward lugs orprojections on the base portion of the joint plate arranged to fit saidnotches, substantially as specified.

2. In a railway rail joint, the combination with the rail sections, ofthe angular joint plate having the base portion upon which the rails areseated, and a vertical portion shaped to fit between the base and treadflanges of the rail, the angular fish plate having notches thereinengaged by projections on the base portion of said joint plate, notchesin the rail also engaged by said projections, spikes driven through saidplates at the inside, and spikes driven against the joint plate at theoutside, substantially as specified.

3. In a railway rail joint, the combination with the rail sections, ofthe angular joint plate having the base portion upon which the rails areseated, and a vertical portion having a longitudinal projection shapedto fit between the base and tread flanges of the rails, the angular fishplate having notches therein engaged by projections on the base portionof said joint plate, notches in the rail also engaged by suchprojections, spikes driven through and against the joint plate, boltsthrough said joint and fish plate, and through the rails, and a lockingdevice for the nuts of said bolts, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

FREDERICK HERMAN.
